True. Thinking ahead to prevent disasters is key. I actually spend a lot of time planning for any time away from tank like a vacation. In past every time I went away for a week, something would happen, like skimmer getting Stuck, or ATO failing, etc,etc. Now I have a WEB cam so I can watch (and this year, FIRST TIME,.... nothing happened)I have been thinking about this since I read it. It is rich with possible analogies and anecdotes. It immediately incorporates into my reefing philosophy. It made me think about approaches to suicide prevention. Certainly one of the chief ways to let the tank meet its demise is neglect. Insensitivity can also contribute. The best way to stop our tanks from dying is spending time with them, getting to know them.
I put this thread together that pretty well lists everything bad that has happened my Kitchen Tank over a decade.
Doesn't include the Dishwasher Soap Contamination Story of last two years. But it does have a couple of doozie events.
